Peptides and combination of peptides for use in immunotherapy against leukemias and other cancers
The present invention relates to peptides, proteins, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present invention relates to the immunotherapy of cancer. The present invention furthermore relates to tumor-associated T-cell peptide epitopes, alone or in combination with other tumor-associated peptides that can for example serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses, or to stimulate T cells ex vivo and transfer into patients. Peptides bound to molecules of the major histocompatibility complex (MHC), or peptides as such, can also be targets of antibodies, soluble T-cell receptors, and other binding molecules.
1. A method of treating a patient who has cancer that presents a peptide consisting of the amino acid sequence of SEQ ID NO: 53 in a complex with an MHC class I molecule on the surface of cancer cells, comprising administering to said patient a composition comprising a population of activated CD8+ cytotoxic T cells that bind a peptide consisting of the amino acid sequence of SEQ ID NO: 53 in a complex with an MHC class I molecule,
wherein said cancer is selected from the group consisting of chronic lymphocytic leukemia, gastric cancer, non-small cell lung cancer adenocarcinoma, squamous cell non-small cell lung cancer, and uterine cancer.
2. The method of claim 1 , wherein the CD8+ cytotoxic T cells are autologous to the patient.
3. The method of claim 1 , wherein the CD8+ cytotoxic T cells are obtained from a healthy donor.
4. The method of claim 1 , wherein the CD8+ cytotoxic T cells are obtained from tumor infiltrating lymphocytes or peripheral blood mononuclear cells.
5. The method of claim 1 , wherein the activated CD8+ cytotoxic T cells are expanded in vitro.
6. The method of claim 1 , wherein the composition further comprises an adjuvant.
7. The method of claim 6 , wherein the adjuvant is selected from imiquimod, GM-CSF, poly-(ICLC), interleukin (IL)-1, IL-2, IL-4, IL-7, IL-12, IL-13, IL-15, IL-21, and IL-23.
8. The method of claim 1 , wherein the activated CD8+ cytotoxic T cells are produced by contacting CD8+ cytotoxic T cells with an antigen presenting cell that expresses the peptide in a complex with an MHC class I molecule on the surface of the antigen presenting cells, for a period of time sufficient to activate said CD8+ cytotoxic T cell.
9. The method of claim 8 , wherein the antigen presenting cell is infected with a recombinant virus expressing the peptide.
10. The method of claim 1 , wherein the cancer is chronic lymphocytic leukemia.
11. The method of claim 1 , wherein the cancer is gastric cancer.
12. The method of claim 1 , wherein the cancer is uterine cancer.
13. The method of claim 1 , wherein the cancer is non-small cell lung cancer adenocarcinoma.
14. A method of eliciting an immune response in a patient who has cancer that presents a peptide consisting of the amino acid sequence of SEQ ID NO: 53 in a complex with an MHC class I molecule on the surface of cancer cells, comprising administering to said patient a composition comprising a population of activated CD8+ cytotoxic T cells that bind a peptide consisting of the amino acid sequence of SEQ ID NO: 53 in a complex with an MHC class I molecule,
wherein said cancer is selected from the group consisting of chronic lymphocytic leukemia, gastric cancer, non-small cell lung cancer adenocarcinoma, squamous cell non-small cell lung cancer, and uterine cancer.
15. The method of claim 14 , wherein the activated CD8+ cytotoxic T cells are produced by contacting CD8+ cytotoxic T cells with an antigen presenting cell that expresses the peptide in a complex with an MHC class I molecule on the surface of the antigen presenting cells, for a period of time sufficient to activate said CD8+ cytotoxic T cell.
16. The method of claim 14 , wherein the cancer is chronic lymphocytic leukemia.
17. The method of claim 14 , wherein the cancer is gastric cancer.
18. The method of claim 14 , wherein the cancer is uterine cancer.
19. The method of claim 14 , wherein the cancer is non-small cell lung cancer adenocarcinoma.
20. The method of claim 1 , further comprising administering to said patient cyclophosphamide, sunitinib, bevacizumab, or sildenafil.
21. The method of claim 7 , wherein the adjuvant is IL-7.
22. The method of claim 7 , wherein the adjuvant is IL-15.
